A lumped parameter dynamic model for U -tube steam generator of AP 1000 nuclear plant was pres-ented.A Matlab/Simulink module was established and employed to simulate the model .The results show that the presented model can well reflect the static and dynamic characteristic of U -tube steam generator .The mod-el can be constituted the real time simulation system of AP 1000 nuclear plant with other models .It also provides a theoretical analysis basis for the steam generator water level measurement , pressure meas...
